Extinction threat growing for mankind’s closest relatives!

Mankind’s closest relatives – the world’s monkeys, apes and other primates – are disappearing from the face of the Earth, with some being literally eaten to extinction.

“Among the African species, the great apes such as gorillas and bonobos have always tended to grab the limelight, and even though they are deeply threatened, it is smaller primates such as the red colobus that could die out first," said IPS President Richard Wrangham.


The first comprehensive review in five years of the world’s 634 kinds of primates found that almost 50 percent are in danger of going extinct, according to the criteria of the IUCN Red List of Threatened Species.

Issued at the 22nd International Primatological Society Congress in Edinburgh, Scotland, the report
by the world’s foremost primate authorities presented a chilling indictment on the state of primates
everywhere. In Asia, more than 70 percent of primates are classified on the IUCN Red List as Vulnerable, Endangered or Critically Endangered – meaning they could disappear forever in the near future.

Habitat destruction, through the burning and clearing of tropical forests, which also emits at least 20 percent of the global greenhouse gases, is a major threat to primates. Other threats include the hunting of primates for food and an illegal wildlife trade.

With the input of hundreds of experts worldwide, the primate review provides scientific data to show the severe threats facing animals that share virtually all DNA with humans. In both Vietnam and Cambodia, approximately 90 percent of primate species are considered at risk of extinction. Populations of gibbons, leaf monkeys, langurs and other species have dwindled due to rampant habitat loss exacerbated by hunting for food and to supply the wildlife trade in traditional Chinese medicine and pets.

Meanwhile, scientists continue to learn more about primates and their role in the world. Since 2000, 53 species of primates previously unknown to science have been described – 40 from Madagascar, two from Africa, three from Asia and eight from Central and South America. In 2007, researchers found a long-rumored population of Critically Endangered greater bamboo lemurs (Prolemur simus) in Madagascar in a wetland 400 kilometers (240 miles) from the only other known home of the species. In total, the species numbers about 140 individuals in the wild.

Despite the gloomy assessment, conservationists point to a notable success in helping targeted species recover. In Brazil, the black lion tamarin (Leontopithecus chrysopygus) was down listed to Endangered from Critically Endangered, as was the golden lion tamarin (Leontopithecus rosalia) in 2003, as a result of three decades of conservation efforts involving numerous institutions. Populations of both animals are now well-protected but remain very small, causing an urgent need for reforestation to provide new habitat for their long-term survival.

As our closest relatives, non-human primates are important to the health of their surrounding ecosystems. Through the dispersal of seeds and other interactions with their environments, primates help support a wide range of plant and animal life in the world’s tropical forests. Healthy forests provide vital resources for local human populations, and also absorb and store carbon dioxide that causes climate change.
